Özet: In this study, hybrid composite materials were produced by reinforcing aluminum matrix, 0.5% GNP (Nano Graphene Plate) powders together with 5-10% - 20% TiB2 (Titanium diboride) powders together using vacuum infiltration method. Afterwards, microstructures of composite materials were examined by SEM and porosity ratios were determined. In the last stage, hardness measurements were made and abrasive wear tests were started. Wear tests; 600 mesh sanding, 0.5 m / s shear rate, 10-20 and 40 N loads were applied, 60-90 and 120 seconds were performed in the test period. According to the test results, the porosity of the composites increased with increasing TiB2 reinforcement ratio. Hardness values increased up to 10% TiB2 and then decreased. Wear losses decreased by up to 10% TiB2 reinforcement ratio and increased again by 20% reinforcement ratio. GNP in the hybrid composites resulted in a decrease in wear losses with increasing test load and time. This is related to the lubricant and lubricant properties of graphene.
